UNITED STATES CHARLES HIGBY, OF NEW BRIGHTON, PENNSYLVANIA.

IMPROVEMENT IN TWINE OR THREAD CUTTING MACHINES.

Specification forming part of Letters Patent No. 127,879, dated June 11, 1872.

l, CHARLES HIGBY, of New Brighton, in the county of Beaver and State of Pennsylvania, have invented certain Improvements in Twine or Thread Cutting Machines to be held in the hand, of which thefollowing is a specification:

The n. ture of my invention relates to the combination, with a spring, of a cuttingedge or knife to be held in the hand, the spring having a tendency to confine and assist-in holding the twine, while the knife, being part of the spring, serves to cut it off. The principal obj ect of the machine is to economize the use of twine or thread, any person being able to cut much closer to the point of tying of packages'than by breaking or otherwise.

Figure l represents the machine with cord in position.

L represents the knife, and M the spring.

After the cord has been led through the eyelets 1, 2, and 3, as shown in the accompanying drawing, and the spring made to press the cord suiiiciently tight at O to keep it from slipping back, it can be easily cut off by simply pressing the thumb on the cord and spring between eyelets 2 and 3 and tilting the edge upward against it. A singleturn around the foreinger before cutting will insure sufficient cord to lay hold of next time.

To enable others to make or construct this machine I give the following as a description for one of medium size.

A piece of sheet-steel is cut four and onehalf inches long, half inch broad at one end and one-quarter of an inch broad at the other end, and bent in such a manner that the narrow end shall be one-half an inch from the edge of the broad end and lay parallel with its upper side, the under side of which is beveled and terminates in a knife or cutting-edge. Eyelet No. 1 serves to balance the machine while being suspended from a ball. Eyelets Nos. 2 and 3 could be dispensed with and a groove on the under side of the small end substituted, but they are preferable where fine cord or thread is used. f

I do not claim the spring or the knife, but the manner of combining the two together for the purpose of confining and assisting to hold the twine at pleasure while same is being cut oft' on the knife.

I claim as my invention- The combination of the knife L and the. spring M, substantially as and for the purpose here-inbefore set forth.
